This ends my series of patches fixing warnings throughout the codebase. Now, there are NO warnings except for unused parameters, tested on GCC 13.1.1 and Clang 16.0.2 with -Wall -Wextra. Fixed dark mode crashing on Windows 8.1, 8 and 7, and removed a need for an export by moving in the function. Any people looking at the Windows code and asking why I didn't use official version querying API's, those typically have some sort of unwanted behavior, plus checking exports to determine versions is shorter.
